Abnormal since night of drinking

Two months ago I had 8 alcoholic drinks over a 10 hour period. I woke up with fast heart rate and have been miserable since with the following symptoms;

- Elevated heart rate, most all day and when waking, was in low 60’s bpm at rest, now regularly 80-90 even at rest

- Shortness of breath, now all day every day having to take deep breaths, not really worse with exertion 

- tightness in chest, left shoulder, sore to touch

- fluttering in chest at times

- jitteryness esp in mornings

- dizziness at times

- sweaty palms at times

Had the following tests;

EKG - fine

Stress Test - ok except heart rate didn’t want to slow down after

Doc says it’s stress and my body is stuck fight or flight, but I feel like something is wrong and causing these symptoms! Any help is appreciated 

It is real simple STOP DRINKING ALCOHOL
